I use my laptop in bed quite frequently and putting the laptop directly on the sheets tends to block the ventilation holes, so I bought this hoping to keep the temperature of my laptop down. Unfortunately the underside of the fan has no guard and is unprotected. In my case it's impossible to put my laptop on it while in bed because the fan will stop. If used on a table or flat surface this is not an issue. Also the LED light while cute, is totally unnecessary.
